Vegan Scalloped Potatoes made with a creamy, cheesy, and rich B├ęchamel Sauce. The onions caramelize while baking and the top of the casserole becomes perfectly crispy. A family favorite holiday side!
Recipe type: Sides
Serves: 6 - 8 servings
  • 1 white onion
  • 8-10 medium Yukon gold potatoes
  • 2-3 sprigs fresh thyme
B├ęchamel Sauce
  1. Soak the cashews in boiling water for 30 minutes or overnight in the fridge. You can skip this step if you are using a high speed blender.
  2. Preheat oven to 400F. Lightly oil a casserole dish or line with parchment paper.
  3. Scrub the potatoes and remove any dark brown spots. Thinly slice the onion and potatoes (the best and quickest way to do this is with a mandolin). Set them aside in separate bowls while you prepare the sauce.
  4. Rinse the cashews. Add the cashews, garlic, bouillon, soy milk, water, vinegar, paprika, and nutmeg to a blender. Blend until creamy smooth. Add the nutritional yeast and flour. Pulse blend until combined.
  5. Warm the sauce over medium-high heat in a deep pan. Whisk until the sauce thickens. This will take about 4 to 5 minutes. Alternatively, you can thicken the sauce in one minute intervals in the microwave until thick.
  6. Layer flat the potatoes in the casserole dish. Add the onions with a pinch of salt and pepper. Repeat for the second layer. Pour ⅓ of the sauce onto the potatoes (see photo for reference).
  7. Repeat the previous step one or two more times (this will depend on the size of your casserole dish). Make sure to the pour sauce in between every two layers. In my casserole dish, I have 4 layers in total.
  8. Pour the rest of the sauce on top. Carefully shake the casserole dish so the sauce gets in between all the potatoes. Garnish with fresh thyme.
  9. Bake for 45 to 50 minutes until golden brown, the sauce is bubbling at the sides, and the potatoes are fully cooked through.
  10. Serve warm with your holiday meal! Enjoy!
